Since version 6 G++ switched to C++11 by default, which breaks some logic
around WITH_CXX11 checks in out CMake files, leading to compilation errors.
This is easy to solve by explicitly enabling older C++ standard when C++11
was not explicitly enabled by CMake options.
However, G++-6 will also use new ABI by default even if older standard was
specified in the compiler options. This is being addressed by a special
define flag.
This tricks made it possible to use new G++-6 without need to recompile
any of pre-compiled libraries.
However, this might break compilation with existing system libraries, which
might already be using new ABI. We can't address this automatically, so
now we simply default WITH_C11 and WITH_CXX11 options to whatever defaults
of the current compiler are. This means, for G++-6 we'll set WITH_CXX11 to
truth. This should make linking with system libraries working just fine,
but to make pre-compiled libraries we still might need to disable CXX11.
This should work fine work for a new environments with G++-6 and install_deps
script run from scratch there, because C++ standard will be the same for
both Blender dependencies and Blender itself.

We don’t require the 3Dconnexion driver framework at build time.
No special link flags or include paths needed.

Using SSE2 intrinsics when available for this kind of conversions.
It's not totally accurate, but accurate enough for the purposes where
we're using direct colorspace conversion by-passing OCIO.
Partially based on code from Cycles, partially based on other online
articles:
https://stackoverflow.com/questions/6475373/optimizations-for-pow-with-const-non-integer-exponent
Makes projection painting on hi-res float textures smoother.
This commit also enables global SSE2 in Blender. It shouldn't
bring any regressions in supported hardware (we require SSE2 since
2.64 now), but should keep an eye on because compilers might have
some bugs with that (unlikely, but possible).

This seems quite useful for the development, so you don't need to wait
all the kernels to be re-compiled when working on a new feature, which
speeds up re-iteration.
Marked as an advanced option, so if it doesn't work so well in practice
it's safe to revert anyway.

Follow convention cmake uses.

This is a bit tricky, find_package(Git) was only used to check if git is installed
and actual git command was assumed to be in the PATH (while ideally it should have
been GIT_COMMAND variable).
This commit makes re-compile output cleaner, especially when using Ninja.
Adding proper GIT_COMMAND to buildinfo.cmake is also possible via argument.

This assumed the OSX SDK version matched the OSX version, which isn't always true.
Also problematic for maintenance and would make building older Blender versions on OSX fail.
Passing in pre-defined OSX_SYSTEM is also supported,
if you have multiple and want to select one.

It'll be nice to eventually go C11/C++11 by default, but for until
then it's kinda handy to be able to build locally with C11 support,

Previously CMake would show many messages about missing libs before checking for a missing LIBDIR.
Now show the error immediately and exit.
Also allow for custom LIBDIR on OSX.

Needed since older versions are unsupported (giving cryptic errors).

OpenVDB is compiled with Blosc support, meaning we should pass Blosc to
a linker now.
Unfortunately, the Blosc has compiled-in crt and pthread library, which
still screws up linking.

even if WITH_OPENVDB_BLOSC is off openvdb still contains 1 reference to snappy so we link with it always

D1751, remove this library since its quite a specific - only supports an older version of this codec.
Also ffmpeg has added support for recent versions of the codec.
|

It is in the archive actually and being installed nicely by the looks of it.

Seems i was the only one who was really up to using it and
i do have gcc-5 finally backported and installed here so
such a fine-tune flags are no longer needed.

Makes sense to keep support of top-range cards "out of the box".

We used to require the 3Dconnexion driver installed at build-time so
this was turned off.
I reworked the code last year to remove the driver dependency so
there’s no reason not to enable this.

Were some missing dependencies in the checks.

Now when doing full build is real easy on all platforms, we can
only keep it enabled for the blender_full configuration.

simulations.
This commits implements OpenVDB as an extra cache format in the Point
Cache system for smoke simulations. Compilation with the library is
turned off by default for now, and shall be enabled when the library is
present.
A documentation of its doings is available here: http://
wiki.blender.org/index.php/User:Kevindietrich/OpenVDBSmokeExport.
A guide to compile OpenVDB can be found here (Linux): http://
